我有两个小时和几分钟:
我从用户那里得到了这个时间。那是你的开始时间和结束时间。
1) 10:00 AM
2) 06:00 PM
现在我必须找到用户工作的总时间。意味着它取 总时间:8:00
我如何得到它?
我在目标C中使用此代码。

我认为它会对你有所帮助。
NSString *time1 = @"10.00 pm";
NSString *time2 = @"06.00 pm";
NSDate *date1;
NSDate *date2;
{
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"hh.mm a"];
date1 = [formatter dateFromString:time1];
date2 = [formatter dateFromString:time2];
[formatter release];
}
NSTimeInterval interval = [date1 timeIntervalSinceDate: date2]; //[date1 timeIntervalSince1970] - [date2 timeIntervalSince1970];
int hour = interval / 3600;
int minute = (int)interval % 3600 / 60;
NSLog(@"%@ %dh %dm", interval<0?@"-":@"+", ABS(hour), ABS(minute));

试试这个!
let calendar = NSCalendar.current
let datecomponents = calendar.dateComponents([.hour], from: start as Date, to: someDateTime as Date)
let hours = datecomponents.hour!
print("hours: \(hours)")

尝试此功能
-(NSString *)startTime:(NSString *)startTime AndWithAndTime:(NSString *)endTime{
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"hh:mm a"];
NSDate *date1 = [formatter dateFromString:startTime];
NSDate *date2 = [formatter dateFromString:endTime];
NSTimeInterval interval = [date2 timeIntervalSinceDate:date1];
int hours = (int)interval / 3600; // integer division to get the hours part
int minutes = (interval - (hours*3600)) / 60; // interval minus hours part (in seconds) divided by 60 yields minutes
NSString *timeDiff = [NSString stringWithFormat:@"%d:%02d", hours, minutes];
return timeDiff;
}
NSLog(@"%@",[self startTime:@"10:00 AM" AndWithAndTime:@"06:00 PM"]);
